Router DNS stopped allowing connections.

Hello,
My Cisco DPC3825, will not act as a DNS server anymore. If I go to network properties and put in my provider's DNS, it works fine. If I connect with just a wireless device, It says "no internet connection".
It was working fine until I started up the machines with wireless connections. Can this be resolved or do I need a new cable modem/router?
Thank you in advance.
John

E4200 - Router would stop working in about 30 mins time

Out of the box this thing was a breeze to setup. That is where the praises end. After the first few devices attached them selves the router would stop allowing internet access. I could still log onto the router and everything appeared fine but there was no internet access. The only solution was to hit the reboot button in the router software or power cycle the router. Then it would work for about 30 minutes. I googled the issue I was having and found it's a common problem. Not sure why this router has such great reviews on here.
What's great about it: Easy to setup
What's not so great: works for only 30 minutes at a time.

You should take a few steps to increase your connection's stability.
Step 1: Reset the wireless router by using the power switch on it or by unplugging it and plugging it back in. You should leave it off for about 20 seconds before turning it back on. This is a good step to take anytime you're troubleshooting your router; it gives the router a chance to refresh the network and reestablish connections with any devices paired to it.
Step 2: Place the wireless router in an ideal location. The higher it is, the better, but don't put it near the ceiling if metal beams or pipes are up there. Metal objects can strongly interfere with the network. Keep it away from large objects, since anything large and solid can obscure its signal.
Step 3: Get as close as possible to the router with whatever device you're trying to connect. The closer you are, the stronger and more stable the connection is.
Step 4: Keep the router and your connecting device away from other electronics. You should especially keep away from phones, fax machines and microwaves, since many of these appliances operate in the same frequency range as wireless routers. Other wireless routers should not be near the Linksys router or your device.
Step 5: Adjust the antenna if it has one. You may need to try putting it in several different positions before you find out what is most effective. If you're connecting to a router on a different floor than you, the antenna should probably be at a 45-degree angle or even completely horizontal.
Step 6: Change the router's channel, especially if other wireless routers are nearby. This is an option that only an advanced user should attempt. You'll need to access the router setting Web page, which is most likely 192.168.1.1; Then go to the Wireless tab and change the wireless channel to 1, 6,9,11...

Cisco 1811W stopped allowing wireless connection of domain laptops

I have a Cisco 1811W that after several years in service suddenly stopped allowing any wireless connection to laptops on the domain. It allows hard wired connections and devices that are just using the wireless hot spot like iPads and Iphones but not devices on the domain. These same laptops connect wirelessly without issue at our other facilities which use the same hardware.
Here is the config file...

It was a two fold problem. There is another stronger Wi-Fi signal that exists at the facility from another entity on a different domain that the two laptops were trying to associate to in lieu of the network signal from our 1811. This could only be seen while watching the Intel wireless Proset app NOT the Windows wireless management app. Then by deleting all other old Wi-Fi networks listed in the Intel Proset app except ours it connected. Also set devices to never connect to the other signal. This was not an issue when I brought the laptop to another faciIity without a competing Wi-Fi signal becuase they would connect using the strongest and ONLY Wi-Fi network signal which was ours.

Is Verizon not allowing connections to alternate DNS servers anymore?

Last night I ran a DNS benchmark test, and a notice popped up saying my ISP was intercepting and redirecting all outgoing DNS requests. I've been using OpenDNS for a year now without any problems, then I found out last night I am not connecting to their servers, so I tried Googles servers, no luck there either.
I called tech support (several times) and no one could give me a straight answer to my question: Is Verizon not allowing connections to alternate DNS servers anymore? I was forced to switch back to Verizon servers, not happy about that.
Can someone please answer my question? Thanks.

I'm on FiOS and I've got no issues using OpenDNS. I have the Quantum router set to use it. Works fine.
I've manually changed DNS on my computer to google's servers. No problems with this, either.

I phone 4s will not stay connected to my wifi it will not set the IP address subnet mask router DNS ETC

My I Phone4s will not stay connected to my home wifi we have 4 other Apple products in house so not a router issue.. Itwill not save all the settings IP address , router, DNS etc and will not allow you to write in manually only the search domains, and DNS only..... any ideas

Thanks Mario but these instructions are for Routers designated 802.11a/b/g/n.
My router is 802.11ac
Can you send info for this? Thanks

DNS suspected in connection pauses

Every 10 minutes or so, my browser on my iMac will stall when trying to load a simple web page (google.com, for instance). It'll load correctly 9 times out 10, then on the 10th, just stall for 1-3 minutes before it loads. I'm almost certain it's a DNS issue, but I've tried completely reinstalling the server software and reconfiguring it, but it still keeps happening.
I've got a small network of 2 10.5.6 iMacs and 10.5.6 G5 server running DNS and DHCP. DHCP hands out the Leopard server first and then the two OpenDNS servers. The default search domain is coldcasey.com.
Running a ping in a separate Terminal window shows no connection failures, so I don't think it's my IP (Comcast). I've done a dscacheutil -flushcache and that doesn't fix anything, so I'm wondering if I've set it up wrong?
Some screen shots of the DNS setup are here:
http://gallery.me.com/brewster3/100292
Below are the results of a forward and reverse dig of my server from my imac and a few to google, as well as the DHCP and DNS log.
Any assistance would be appreciated!
Thanks.

Queries to DNS servers are tried in the order listed as set in the Network prefpane. The values listed there are stored in the /etc/resolv.conf file and are updated by the Network prefpane.
If you do this in Terminal.app:
more /etc/resolv.conf
it should display:
nameserver 10.0.123.254
nameserver 208.67.222.222
nameserver 208.67.220.220
If you change the order in either your DHCP server -and renew the lease- or in the Network prefpane and run the command again, the order will change in /etc/resolv.conf. Clients will only query lower ordered name servers if the higher ordered one is busy with a query at the time they make a query or if multiple DNS servers are setup with load-balancing to round-robin the queries. On a small network like yours, you won't have that problem.
Where you are running into a problem is this, the domain that you have selected for your home network, coldcasey.com, has its SOA with DNS servers at name.com. You also have your internal DNS as the SOA for that zone. You send out queries from your internal DNS server as the SOA for that domain. Your firewall/router is passing inbound requests from the servers that you're connecting to in an attempt to retrieve zone information from your internal DNS. Your DNS is blocking that request. That's why you are seeing this:
20-May-2009 17:48:36.385 client 208.76.70.146#38920: view com.apple.ServerAdmin.DNS.public: query (cache) './A/IN' denied
in your logs. You need to block inbound port 53 TCP/UDP requests to your DNS at your router or firewall. Your firewall setting should allow inbound responses to outbound DNS queries on port 53 TCP/UDP. This will not affect your internal DNS from querying other servers. You need to change the zone for your internal network to something other than coldcasey.com.
In Server Admin under DNS, select your DNS server's settings -the 'gear' icon- and set recursion only for 'localnets'. You really don't need any 'forwarders', as your server will resolve all lookups that it isn't authoritative for with external DNS servers. Your devices with fixed IP addresses should be configured with only your internal DNS in their network config.
Also, configure your DHCP server's DNS setting to list only your internal DNS server -as adding forwarders only slows down resolution as they will pass queries onto the same authoritative DNS servers that yours would if it receives queries that it is not authoritative for. If you have a router or a WAP connected to your network, turn off the DHCP servers in those devices.
You should also configure the DHCP scope to hand out a few address on your home network instead of the entire address range, say from 10.0.123.200 - 10.0.123.253, that should be more than enough for several VPN clients -or a LAN party. Any static IP numbers for internal devices can be set in the range from 10.0.123.2 - 10.0.123.199 -plenty of numbers there and you won't have to setup static mappings.
When using 'dig' to resolve IP addresses/names, the '-x' option, is for reverse lookups -that's why you're getting no information when you do this:
dig -x www.google.com
the correct usage is:
dig www.google.com
Which returns this:
;; ANSWER SECTION:
www.google.com. 518838 IN CNAME www.l.google.com.
www.l.google.com. 134 IN A 64.233.161.147
www.l.google.com. 134 IN A 64.233.161.99
www.l.google.com. 134 IN A 64.233.161.104
in the 'ANSWER' section. If you were to do this:
dig -x 64.233.161.147
it would come back as:
;; ANSWER SCTION:

or something similar/different as they have their servers DNS round-robined for load-balancing.
For your internal network, if you do this:
dig 10.0.123.254
you get no answer because that's not a correct query.
If you do this:
dig -x 10.0.123.254
it should return:
;; ANSWER SECTION:
254.123.0.10.in-addr.arpa. IN PTR server.coldcasey.com.
in the ANSWER section. Therefore, if you do this:
dig server.coldcasey.com
it will return:
;; ANSWER SECTION:
server.coldcasey.com. 134 IN A 10.0.123.254
which would be correct.

Addition of third computer in network causes router to drop internet connection (is the problem Dropbox???)

This is not specifically about MacBook Pros, per se, but since all of the communities are based on specific products, I chose it since it applies to two of the devices concerned.
We have a LINKSYS WRT54G router in our home connected to cable internet.
We normally run a number of iOS devices on it at any given time (iPhone 5, iPhone 4s, iPhone 4, two iPad 2nd gen., one iPad Mini with Retina), and almost at all times, an Intel MacBook Pro on 10.6. We sometimes also have an Intel MacBook (black) on 10.6. These all live in harmony just fine. Both laptops have Dropbox on them, but signed in on different user accounts.
I used to have someone working at my house quite often on an Intel MacBook Pro on 10.7, also using Dropbox (but signed into a unique account). Whenever she had her computer on in our house, it would often cause the network to just drop the internet connection suddenly. The network would still have a strong signal, internet just wouldn't work.
We never quite figured it out. We had to reset the router constantly. It was NOT the modem -- you could reset just the router and the results were the same as if you had reset the modem. I didn't pursue a fix since she has since stopped working here.
Recently we just added an Intel iMac on 10.6 to the house, and it is doing the same thing. The only difference is this time, it's logged into the same Dropbox account as my MacBook Pro. At first, it seemed as if there was an issue if both were trying to update at the same time. When I paused syncing on one computer or throttled the upload/download bandwidth, it seemed to get better. However, lately, I am not syncing any large files -- or any files at all, it seems, sometimes -- and I also kept one machine on throttled connections, while a THIRD machine is even off completely...and it's still kicking the internet connection off.
Any ideas? I'm getting really tired of re-setting it every so often.
Thank you!

Also, there are no other networks we pick up here. Sometimes, we randomly get the neighbor's, but it's protected and we don't ever join it.
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.

Mimo access points with Static WEP security do not allow connection speeds above 54mbps

I am getting this message:
Access Connections - Mimo access points with Static WEP security do not allow connection speeds above 54mbps
If I switch from WEP to WAP i do not get the message but I still only get 54mbps speed. I have a Linksys Wireless-N Broadband Router. Is there a setting that I am missing???

Yes you need to use WPA-AES or WPA2-AES, or no encryption, to go faster than 54Mbps. This is part of the 802.11n spec.
That's not so bad, because if you have the right 802.11n card and use the right settings you can go up to 300Mbps!
What bites is that the 802.11n card which comes with X-Series ThinkPads is the Intel 4965AGN. It does not support the broader 802.11n 40MHz channel width option, limiting the top speed to 130Mbps .
The new ThinkPads based on the Montevina/Centrino 2 platform will most likely use the Intel WiFi Link 5100/5300 802.11n/WiMax cards, which I hope will fix this, coz I'm going to buy one!
I don't work for Lenovo. I'm a crazy volunteer!

DNS stopped updating

NW 6.5.8

Noticed recently that DNS stopped updating
Local client get the IP correcty, but the info is not writen/updated in DNS

Help
WiFi only works close to router, DNS fail, Signal Bars present but Safari says no Internet, I've deleted and re-added through to reset and full reset, I had no problem with 4.3.2 only 4.3.3 both my iPhone4 and my iPad2. I am now beside router - no problem, but go 20 metres and WiFi becomes unstable. Only way to get either to work is disable WiFi either as a Hot Spot or turn it off and use the 3G connection. This worked with 4.3 & 4.3.2 what has gone wrong? I raised it at the Apple Store in Belfast as a problem but was told that there was no problem with Apple but I must have a faulty router - yeah - that's a lot of faulty routers, my home, my office, my holiday home, Starbucks, my friends house, my son's house. I've tried all the 'fixes'. I think it is a plan to force us to buy Apple Routers

Two ways out, I added two more Belkin Access Points in my house in Spain so that I'm not more than 10Mtrs away, (Reinforced Concrete & solar glass 2010)
I bought 3 Apple Airports, 1 x Extreme and 2 x Express (1 as a hard wired AP, 1 as an extender) for my other house (Brick construction 1930's)
Everthing now works perfectly, as I said 'an apple plot', so either blast them with signal or visit your nearest apple store.
Early beta iOS5 (iPad) is also much inproved in Beta 3, I have not had any problem with 'Lion'
Happy hunting!

"Closed" port allowing connections

I installed Transmission to get distro .iso's even though I'm typically wary of P2P programs. One reason is the interesting behavior that I'm seeing when Transmission is open. I'm using the iptables.basic rules that come with the package. An nmap scan from another computer in my wireless network shows that the connection port is closed but when I scan my IP address (not localhost) from my computer, it says that the torrent client port is the only one that is open which is consistent with the fact that it is also accepting connections (even without any port forwarding enabled on the router or my machine). I would like to at least have a choice whether or not I allow connections to my machine but the only option seems to be not using Transmission at all. Is this the case? If not, why is the port closed according to external tests yet it is accepting connections?

upnp is the only thing I can come up with.

Wifi Connected but not allowing connection to internet....

Ok for starters I am by no means computer illiterate. I have several industry certifications and have worked in IT in one form or another for over 10 years. That being said I have tried all the obvious solutions to fix this issue. So please save your effort in telling me to flush dns servers, check connection settings on clients, run ipconfig with various switches, etc... all this has been done and failed. That is not to say I know everything, because I don’t, I’m just saying that I have tried all the obvious troubleshooting routes.
Now… on to my issue. I have a WRT54GS ver. 5 and it has worked flawlessly for several years now. My machine is hard wired to the access point and I have no troubles connecting to the internet via said PC. The wireless I use for my wife’s laptop and my iPhone. I use mac filtering and WPA Personal with TKIP, dhcp is disabled and IP's are assigned manually via TCP/IP settings in windows. Two days ago my wife complained that she was unable to connect to the internet despite the fact that she had a solid connection to the AP. After checking her machine and finding everything in order in terms of the connection settings I also discovered that my iPhone was also unable to connect to the internet via Wi-Fi, again despite a strong connection to the AP. This led me to believe that the issue lied with the AP since nothing had changed on the client machines and all the connection settings were correct. I am able to ping the AP from the client but it is not routing traffic to the internet.
That brings me to troubleshooting the AP. I logged in and verified that all settings were as they had always been in the router, not one thing had changed. So to make absolutely sure it was not some setting in the AP that had been changed somehow I reset the router to defaults and re-configured it EXACTLY as it had always been. Still no love. I also tried the following to further troubleshoot the issue with no luck:
Clearing WINS and TCP/IP stack in windows on the laptop.
Disabling WPA and connecting with no security save MAC filtering
(yes I made sure that MAC filtering was set to permit and that all MAC addresses were correct)
Upgraded to the latest firmware.
Unplugged wireless phones throughout the house and cycled through all 11 channels to rule out interference.
I guess what I am now trying to figure out is whether or not the routers Wi-Fi is bricked. Is it possible for the Wi-Fi to be bricked but still be able to connect to the Wi-Fi network with a strong signal and for wired to work just fine? I would think that if the Wi-Fi was kaput that one would not be able even connect to the AP via wireless. I am to the point now where I’m about to say screw it and just go buy a Wireless N router and be done with it. But to be honest I am a little leery of Linksys now if a two or three year old router is bricked without warning or any apparent cause. Even though I have used Linksys products for the entirety of my IT career, I am now having second thoughts about going with cisco products if indeed it is bricked and I have to go out and buy another AP. Any help the community here can offer would be much appreciated, I don’t mind getting a new AP as the N speeds would be a plus but I want to make sure that all hope is lost for the WRT54GS before I do.

Thanks for your reply.
Yes, as stated in the OP all clients wired or otherwise have IP's and DNS info manually entered in windows TCP/IP configuration. All of the IP info has been the same for years and it works fine on my machine (hard wired) with the only difference being the last octet of the IP, subnets and DNS settings are the same on all clients.
All 4 clients (My PC, Laptop, Iphone, and wireless printer) can all ping both ways without issue. As I mentioned before the wireless clients connect to the AP just fine and all settings are verified correct. My WLAN is still working flawlessly and I can connect to and view all clients and shares. The issue seems to lie with the WiFI routing to the internet: I can connect to the internet from the wired PC and all the clients on the local network have connectivity, the only issue I have is that the wireless clients (in spite of a working connection to the AP) cannot seem to get thorugh the internet. However I did change the RTS and Fragmentation to 2304 and the beacon to 50 as you advised and set the DNS servers to what you listed on the wireless machine and was still able to ping back and forth but had no connectivity to the internet.

Router reboots upon wireless connection

I have the Linksys WRT54GS wireless router with firmware version 4.71.1. Whenever I try to connect to my wireless network, or if I even try to find it with the "View Wireless Networks" window, my router resets, thus dropping connections with my other computers (wired and wireless) and the internet. Once re-connected to the other computers and the internet, I can usually connect my wireless computer. Also, all my wireless computers have no trouble connecting automatically to my network... it's just when I want to (or need to) connect manually that my router reboots. I have tried several things (too many to list) to try and stop it, however, I was just curious as to why this would happen (FYI: my router is very stable other than that, and does not drop connections at any other time). If anyone has any insight or instructions on what I could do, please give me a hand; this issue is quite annoying at times.

try reflashing/upgrading firmware on the router, after reflashing firmware hard reset the router back to factory default settings and reconfigure it according to ISP settings... logon to router's setup page, edit the wireless security e.g. wireless channel to 11, go to advanced wireless settings and reduce beacon intrval to 50, fragmentation and RTS threshold to 2304, transmission rate to 54mbps check whether it works for you or not.

Router and access point connected to FIOS router

Here's my situation. Just installed Verizon Fios which supplies their own Actiontec Wireless router. I have an existing network which comprises a WRTG54Gv6 which was connected to a DSL modem for internet access originally and a WAP54G accesss point as a Repeater to extend the network wirelessly. I have quite a few wired and wireless connection to this netwrok and wish to retain these devices. My question is, based on where I had to connect the new FIOS router(which is where the access point is) can I connect the WAP54 to the FIOS router(through a switch) and allow the combined WAP54/WRT54G network to still provide my network services and deactivate the wireless service from the FIOS router. How do I configure the FIOS router, the WRTG54 and the WAP54(if change neded).
Thanks in advanced if anyone can help.

Easiest way to configure the Verizon FIOS with Linksys is - Leave the Verizon FIOS unplugged from the Linksys Router and disconnect it's power cable.
1. Connect a computer to the Linksys Router it's Internet Port...
2. Access the web interface of the Linksys Router, change it's default address to 10.10.10.1 and leave it's DHCP Server Settings 'Enabled'. Once done you should Power cycle the Linksys Router.Don't change the Router Mode.
3.Connect Verizon FIOS from it's Ethernet Port to the Linksys Router on the Internet Port.
4. See if you can access the Internet...
You can also have a look at this link to connect two routers.However, both the router's used in the link are linksys routers but you can still follow the link.

Why is my router attempting UDP stealth connections?

This firewall log entry shows my Linksys router attempting a stealth connection via UDP to my local computer.
I've never seen such a thing.
Any thoughts on this?
+Jul 9 20:42:48 mycomputer Firewall[39]: Stealth Mode connection attempt to UDP 192.168.1.140:64501 from 192.168.1.1:53+

UDP port 53 is normally DNS.
Ignore the "stealth mode" bits - as I understand it (but I would be interested in any correction), stealth mode properly means that a device is set up to ignore ping requests. There is no such thing as a "stealth mode connection".
Indeed, properly there is no such thing as a UDP connection either - UDP is a connectionless protocol. A device receives a UDP request and may send a UDP response.

Router DNS stopped allowing connections.
